measuring shuttlecock speed?
how do the professionals court managment measure the speed of each rally or smash at the end? are there sensors or cameras.. or what is it?
because i'm watching the european finals 09 and each time the rally is over, a number gets displayed on the four corners of the court and im pretty sure it indicates the speed which the shuttle was travelling at. so how do they do it?

I'm guessing it's the same way as they do in tennis - radars. There is a way of working it out from films though.

anyone know the science behind it and maybe some use of graphical presentation would be helpful.

thanks for the research, i think they calculate it thru video... you know... distanced travel over time...
hmm... we'll have to see, any experts here that have had experience with this?

with tennis i heard from the commentary that the speed is captured when the ball leaves the hitter's racket .. therefore the highest speed as the ball will always be losing speed along the way ..
i believe it is the same with badminton coz no way the shuttle can maintain a speed of over 300kmh (super smashes) average especially as the shuttle loses speed much much faster as compared to the tennis ball

I also was trying to figure this out, especially I wonder about what distance is measured.
I t has to be the first few meters?
If I find out anything more, I'll post it here

Dear Mr. van Veen
Thank you for your interest in my article. So far, I’ve never heard about any official speed measurements in badminton and hence about any standards in that. However, there are some rumors that other teams also used the shuttle travel distance of one meter over which the shuttle speed is measured.
Dear Prof. Dr. C. Stamm,
I read your article (ShuttleSpeed - High-speed real-time video processing in badminton) about measuring shuttle speeds with great interest.
I was wondering: is there a conventional / normal travel distance that is used standardly as the distance over which the shuttle speed is measured.
Like, in your article, one meter? I'm always wondering how I'm to interpret the displayed shuttle speeds given in broadcastings of major events.
Thanks for your time!
